Metal Detectors

Choose based on target types (coins, jewelry, relics), discrimination settings to ignore common junk, coil size for desired coverage and depth (larger coils for deeper, smaller for tight spaces), and portability/weight for comfort while walking around a yard

Key features are discrimination control, adjustable sensitivity, ground balance for mineralized soil, pinpoint mode to locate targets precisely, and a waterproof or splashproof coil if you expect damp conditions

Entry-level hobby detectors are commonly found under $150, mid-range models with better depth and features typically range from about $150 to $400, and higher-end or specialist units cost more depending on advanced electronics and coil options

Yes, but avoid digging near visible irrigation lines and call local utility services before any deep digging; use a small digging tool and probe carefully to minimize damage to turf and underground systems

Depth varies by detector, coil size, target size, and soil conditions; small targets like coins are often detected a few inches deep, while larger objects can be detected several inches to a foot or more in favorable soil with a properly matched coil

Rinse or wipe coils and control housing after damp or dirty conditions, check and replace batteries as recommended, store in a dry location away from extreme temperatures, and periodically inspect cables and mounts for wear

Waterproof coils are useful if you plan to search in wet grass, puddles, or shallow streams, but they are not essential for dry lawns; ensure any electronic housing rated non-waterproof is kept dry even if the coil is waterproof
